As An Immortal, I Only Learn Forbidden Skills - Chapter 1283 -

Most people think getting summoned to another world or reincarnated as a Hero is a dream come true. Power, fame, glory, money. What’s not to love?Jin thought the same… until it happened for the 500th time.After centuries of saving and destroying worlds, he just wanted to rest. But when two supreme beings refused to end his cycle of reincarnation, Jin took matters into his own hands and tried to summon himself back home.The result? His spell had gone wrong.Now he’s stuck in a world almost identical to his old one. Except this time, it’s ruled entirely by women. But when he thinks he can finally retire, he gets blackmailed into becoming one of the 'Heroes' of the world.Discord: https://discord.gg/ERp9NF59f5

In my former life, I dedicated most of my adult life to achieving my goal of exploring the stars. Unfortunately, due to circumstances outside my control, my life abruptly ended leaving my dream unfulfilled. Thanks to the intervention of the Big Guy Upstairs, I was given a chance to achieve my dream though the one who reincarnated me screwed me over. Unlike the futuristic type of world I wanted to start in, I ended up being born in a medieval, magical world as the third son of a regional baron. All I can do now is Dungeon Crawl for ancient technology in the hopes that I find a ship or technology to get me off this damn world!

We have all heard the legends of great wizards, but do we know how those stories begin? Ardan Egobar, a young man living in a remote corner of the New Monarchy Empire, does not. He doesn't realize that this story is about him. Not yet...In a world where steam locomotives chug along iron rails, where massive airships hover in the skies, where in the cities you might encounter orcs in suits involved in organized crimes, dwarves with cigars controlling major banks, or elves strutting down fashionable boulevards, where humans have built vast nations on the brink of a world war, almost anything seems possible.Maybe, in such a world, even an ordinary young man, the last of the mountain hunters, might one day become the greatest wizard in history.
